La Marzocco GS3 Steam Valve Rebuild Kit Complete set of wearable parts for rebuilding the La Marzocco GS3 steam valve in one kit. SPECIFICATIONS Includes B.1.004.2, B.1.004.3, B.1.004.4 and B.1.004.5 valve components, two H.1.004 o-rings (MZ_299), two B.1.004.7 springs, a B.1.004.9 seal assembly, and an H.2.002 gasket (AZ_5) COMPATIBILITY Fits: La Marzocco GS3 steam valve INSTALLATION Moderate-difficulty rebuild; a technician-comfortable DIYer can handle it, otherwise we recommend a technician. PRO TIPS Replace every part in the kit at once rather than cherry-picking - the springs and seals wear together, and mixing old and new components shortens the life of the rebuild.
The catalog often lists the same model at several merchants — worth a price check before you buy.
